Is there a definitive answer as to why dogs do that kicking/digging thing after they pee? I’ve mostly read that it’s part of marking behavior - spreading the scent. But I do remember a study done years ago (like in the 80’s) that was somewhat inconclusive. The study used unneutered dogs, dogs neutered early, and dogs neutered after maturity. They couldn’t find a pattern.
Interestingly, my ACD cross (neutered in early puppyhood, as he was born at a rescue) NEVER does this - he pees or poops and then is ready to move on. My hound, neutered at around age 1-2, can flat out destroy some landscaping post-pee, and you’d better not be standing directly behind him or you risk a divot (or worse - he’s been known to fling turds hither and yon after a poop) in the eye.
I’ve seen some dogs do it totally unrelated to bathroom activity, and I have NEVER seen a female dog do this.
